Specification of Letters Patent.

Patented July 3, 1911 "3.

Application filed July 1, 1916. Serial No. 107,167.

To all whom it may concernf Be it known that I, GEORGE J. FENN, subjectof the King of Great Britain and Ireland, and resident of London, E. C.,England, have invented certain new and useful Improvements inType-Writing Machines, of which the following is a specification.

My invention relates to typewriting machines and particularly to platenor work sheet controlling means.

The main objects of my invention, generally stated, are to providecomparatively simpleand efficient means of the character specified, andby which a work sheet or sheets, an envelop and the like may, by itsingle operation, be advanced any predetermined extent to bring it intoposition to receive the first line of writing; by) which thework sheetor sheets may be advanced a predetermined distance under control of oneauxiliary device, and may be retracted a predetermined extent undercontrol of a separate and distinct auxiliary device, for producingcondensed record billing work and the like, quickly and eifectively; by

which a' greater extent of feed of the work sheets in one direction may,if desired, be effected by one of said auxiliary devices, than isefi'ected in the opposite direction by .the other of said auxiliarydevices.

To the above and other ends which will hereinafter appear my inventionconsists in the features of construction, arrangements of parts, andcombinations of devices set forth in the following description andparticularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference charactersdesignate corresponding parts in the various views,

Figure 1 is a fragmentary front view showing the embodiment of myinvention in a No. 20 Yost machine, the View illustrating only so muchof said machine as may be necessary to arrive at an understanding of myinvention.

Fig. 2 is a left-hand end view of the same with parts sectioned away.

Fig. 3 is a right-hand end view of the same with parts sectioned away.

Fig. 4.- is a transverse sectional view showing some of the details ofconstruction, the

taken on the line y-y of Fig. 3 and looking in the direction of thearrow at said line.

I have shown my invention in the present instance embodied in a No. 20Yost machine in which the invention may be readily incorporated withoutmodifying or materially modifying the structural features of saidmachine as they now exist. It should be understood, however, that theinvention may be embodied in various styles of typewriting machines, andthat accordingly various changes may be made in the construction andarrangement of the parts.

I have shown only the platen frame of the usual No. 20 Yost machine andsome of its regular equipment together with the special devices of myinvention; this being sufiicient to illustrate my invention.

. The carriage of this machine is disclosed in the patent to A. Smith N0. 1,050,245, dated Jan. 14, 1913.

The platen frame, comprising end plates I the platen. Such line spacingmechanism is disclosed in the patent to A. W. Smith No. 911,275, datedFeb. 2, 1909, and includes a line spacing wheel 10 connected with theplaten in the usual manner and engaged by the line spacing pawl 11. Thispawl coacts with the wheel to move it and platen a distance of one, twoor three teeth of said wheel, depending upon the position of acontrolling device 12, which may be turned to any one of three positionsby a head or finger piece 13. The line spacing pawl 11 is carried by aline spacing lever 14 pivoted to a bracket arm 15 projecting from theend plate or frame 2.

' In addition to the line spacing mechanism I have provided auxiliarydevices separate and distinct from each other, and operableindependentlyof each other, one for turning the platen a predetermined distance ofmore or less than an entire revolution in one direction at eachactuation, and the other for turning the platena predetermined distanceof more or less than an entire revolution in the opposite direction ateach actuation. In the present instance these devices are locatedatopposite ends of the carriage The auxiliary devices in question aremuchalike in construction except that they are operable in oppositedirections, one being effective only to give a backward rotation of theplaten, whereas the other is effective only to give a forward rotationof the. platen.

The device at the right-hand end of the carriage is effective to producea backward rotation of the platen and will first be described. In thepresent instance the line spacing wheel 10 is shown provided withtwenty-five teeth. I A pinion 16, with a corresponding number of teeth,is provided with a hub 17 and is secured by set screws 18 to a hollowshaft 19. This shaft receives a bearing in the end plate 2 of the platenframe and is received at its inner end in a hub 20 of the right-handplaten head 21, and set screws 22 secure the hollow shaft 19 to saidplaten head. The pinion 16 is thus fixedly secured to the platen and isconcentric therewith. A gear 23 is supported to turn on a fixed spindle24, as best shown in Fig. 4, this spindle being off-set from the axis ofthe platen. The spindle 24 is in the nature of a headed shoulderedscrew, the threaded end of which is received in a tapped opening in theend of one of the-usual tie-rods 3, and the shoulder on the screw bearsagainst the adjacent end of said rod. The head 25 of the screw ispositioned outside of a disk or disk-like support 26 to hold the partsagainst outward displacement. The disk 26 is apertured to receive thespindle 24 so that the disk is supported in part by said spindle and inpart by a bracket arm 27 formed on the disk and which is secured by ascrew 28 to the end plate 2. An arm 29 is located intermediate the'diskand gear 23 and is provided with a hub-like portion 30 apertured toprovide a bearing on the spindle so that the arm 29 may turn"concentrically with the gear 23 around the spindle 24. The arm 29 1stapped to receive the threaded end of a shouldered thumb screw 31. Thisscrew extends freely through a slot 32 in the disk 26, said slot beingformed concentrically with the gear 23. A shoulder 33 on the thumb screwbearsagainst a washer which in turn bears against the outer face of thedisk 26. It will be understood that the screw 31 constitutes a bindingscrew which, when tightened, binds the arm 29 against the disk 26 andholds said arm in the position to which it may be adjusted around thespindle 24.

The upper end of the arm 29 is bent inwardly at 34 and overlaps andextends beyond the gear 23 and constitutes a stop for purposes whichwill hereinafter more clearly appear. I

.A hand actuated controlling device or crank 35, preferably of greaterradiusthan the gear 23 and the platen, is formed with of the gear awaymined by t a hub-like portion 36 apertured to receive a bearing on thespindle 24 atthe inner side of the gear 23. A spacing sleeve 37 ismounted on the spindle intermediate the crank 35 and the end plate 2 ofthe platen 7 frame in order to maintain the parts against lateraldisplacement along the spindle in one direction. A coiled spring 38surrounds the spacing sleeve 37 and is secured at one end,

coiled around a screw pin 44 carried by the crank 35. One end of thisspring is secured, as at 45 to the crank, the other end 46 of the springbeing seated in the notch in the pawl 41. This spring tends to force thepawl into engagement with the teeth of the gear 23. An adjustableabutment, designated as a whole by the reference numeral 47, is adaptedto receive the threaded end of a headed screw 48 which extends throughthe slot 32, the head of the screw bearing against a washer 49 which inturn bears against the outer face of the disk 26. The abutment 47 isthus mounted for adjustment along the slot 32 concentrically with thegear 23." The abutment may be held in its adtightening the screw 48,thus effecting a binding engagement between the abutment and the disk26. This abutment is provided with an engaging finger 50 which extendsover the teeth, of the gear 23 and in the path of the pawl 41 as thelatter is retracted with the crank in its movement j usted position by.back to normal position, shown in full lines in Fig. 3. The abutmentisadjusted so that just before the crank reaches this position the'pawlwill be lifted against the force of its spring 43 and disengaged fromthe teeth 23, so that the platen, its pmion 16, and gear 23 are free tobe turned in either direction independently of the crank. However, atthe first part of the operative stroke of the crank from the full to thedotted line positions in Fig. 3, the pawl will be moved from theabutment and allowed to engage the teeth of the gear 23. This stroke ofthe crank therefore is effective to turn the gear and pinion 16, andthus effect a backward rotation of the platen. The extent of rotation ofthe platen thus effected is determined by the stroke of the crank, andthe extent of stroke of the crank is predeterlfe adjustment of the stop34. The return movement of the crank to normal position is effectedindependently of the gear 23 and, as hereinbefore pointed out, 1s.

effected automatically by the spring 38 when Lasaesa the crank isreleased. During this return movement of the crank the pawl 41 will moveidly over the teeth of the gear so that said crank is only operative onthe gear and platen during the movement of the crank in one direction.

The crank is limited in its return movement to normal position by aportion of the crank, which is in the nature of a projection 51 thereon,engaging the hub 17 of the pinion 16, the engaging parts acting as stopsto limit the movement of the crank in one direction. A finger pieceorhandle 52 may be provided on a crank to facilitate an operationthereof. 7

It has been hereinbefore explained that in the present instance the linespacing wheel and pinion 16 each has twenty-five teeth thereon. The gear23 has, say, eighty teeth. It will therefore be understood that thegearing intermediate the crank and platen constitute multiple gearing bywhich the motion transmitted from the crank to the platen is multipliedso that a comparatively small angular movement of the crank will producea comparatively large angular movement of the platen, and a partialrotation of the crank may turn the platen through more or less than anentire rotation thereof. F or example, with the stop 34 adjusted to theposition shown it may be assumed that an actuation of the crank from thefull to the dotted line positions in Fig. 3 will turn the platen througha complete backward rotation, less a distance corresponding to twosingle line spaces, or two teeth. of the line spacing wheel 10. It willbe readily understood that a further backward adjustment of the stop 34from the position shown will enable the platen to be turned much fartherat each actuation of the crank 35.

The construction and operation of the controlling device at the oppositeend of the carriage are much the same as described above except, ashereinbefore explained, the parts move from normal position in adirection opposite from that of the parts just described, and areeffective to produce a forward movement of the platen instead of abackward movement thereof' Therefore, it is not deemed necessary torepeat the description of this device, except in so far as it may differfrom the device previously described. The same reference characters thatare employed to designate the parts of the device at the right-hand endof the platen frame will be employed to designate the correspondingparts at the left-hand end thereof, with the addition in each instanceof the numeral 1 before the reference character previously employed.Thus, the crank of the right-hand device is designated by the referencenumeral 35 whereas the crank of the left-hand device is designated bythe reference numeral 135. The other corresponding parts are designatedin a like. manner. p

The crank 135 of the controlling device at the left-hand end of theplaten is limited in its movement back to normal position by theadjustable stop 134, whereas the projection 151 on the crank co-actswith the hub 117 of the pinion 116 to limit the operating movement'ofthe crank. Moreover, the stop 134 not only arrests the crank 135 in itsmovement back to normal position, but also co-acts with the tail piecelatl on the pawl- 141 to lift it out of engagement with the gear 123just before the crank reaches normal position.-

The operation of this device is the same as that previously describedexcept that the movements of the parts are reversed so that a forwardmovement of the crank from the normal position results in a forwardmovement of the platen. The extent of this movement is determined by theadjustment of the stop 134, the return movement of the crankindependently of the platen being antomatically effected by a spring 138after the crank and platen are arrested and the crank released by theoperator.

In the present instance I have shown the stop 134 adjusted so that eachoperative stroke of the crank 135 is effective to turn the platenforward one revolution, or two single or one double line space more thanit is turned backward by the crank 35, with the parts adjusted as shownand for reasons which will hereinafter appear.

It will be understood from the foregoing description that the cranks atopposite ends of the platen are normally disconnected from the platen sothat the latter is adapted to be turned either forward or backwardunlimited extents independently of either of said devices; that saiddevices therefore do not interfere with the feed movement of the platenunder control of the ordinary line spacingmechanism: that said cranks ordevices are operable independently of each other, and that each crank iscapable of turning the platen and arresting the movement thereof in onlyone direction, one crank controlling the movement of the platen in onedirection and the other crank controlling the movement of the platen inthe opposite direction; that the throw and arrest of one of said cranksis effected entirely independently of the other so that the platen maybe given a longer extent of turning movement in one direction by onecrank than is given the platen in the opposite direction by the othercrank.

- By reas of these facts the devices are capable of a wide range ofuses. For ex- .ample, if it is desired to feed envelope,

blanks or other work sheets into the machine so that each sheet will bebrought by a position to receive the first line of writing, whereversuch line is to appear on the work sheet, it is merely necessary toadjust the stop 134 in position so that a single sweep of the crank 135to the dotted line position will bring the work sheet to the properposition. Whether it requires one or more revolutions of the platen toeffect this result is immaterial since the crank is effective to producethe required extent of movement. Work sheets are thus successively fedinto the machine, each sheet requiring a single operation of the crank135 to bring it into position to receive the first line of writing. Thesheet is then written in the ordinary manner and removed when completedand the next sheet is fed into'the machine with the aid of the crank135.

One method of using the construction for single operation into producingcondensed record billing work,

is to first adjust the stop 134: so that a single actuation of the crank135 will feed a bill sheet forward in proper position to receive.

the first line of writing. It may be assumed for example that thisrequires a complete revolution of the platen, so that the stop 134 isadjusted to the posltion represented in Fig. 2.

The stop 34 may now be adjusted to a position where the throw of thecrank 35 will efiect a backward movement of the platen a distance of,say, two line spaces less than an entire rotation, as represented inFig. 3.

A. bill sheet, record sheet and interposed carbon sheet may now beintroduced into the machine, the requisite lead of the bill sheet overthe carbon and record sheets being given, if desired, so that the firstline reproduced on the record sheet will appear 4 near the upper edgethereof.

A single sweep of the crank 135 from the full to the dotted lineositions in Fig. 2 is effective to turn the p aten and bring all sheetsforward together into position Where the bill sheet is properly locatedto receive the first line of writing. The crank 135 returns to normalposition when it is released by the operator and the operator proceedsto write the bill in the usual manner, a carbon copy of the entriesbeing produced on the record sheet beginning near the top thereof. Afterthe bill is. completed it is removed without disturbing the record andcarbon sheets, and the crank 35 is turned from the full to the dottedline positions in Fig. 3. The effect of this is to produce a backwardmovement of the platen to a position where a new bill sheet may beintroduced and fed forward with the record sheet and interleaved carbonsheet at the next actuation ofthe crank 135. When said actuation of thecrank 135 is completed the bill sheet will be positioned so as toreceive the going that the first line of writing thereon and this line,when written, will be reproduced on the record sheet a distance of woline spaces from the last line of the copy of the preceding billthereon. This is due to the fact that in retracting the record sheet,through an operation of the crank 35, it is moved two line spaces lessthan it is moved forward with the bill sheet by an actuation of thecrank 135.

It will be understood therefore that provision is thus made foreffecting any desired extent of spacing between successive bills on therecord sheet without the provision of any complicated specialautomatically .operating means to effect the result. The operator istherefore relieved from effecting a double space line spacing operation,with the aid of the line spacing mechanism, afterthe completion of eachbill and is relieved of the necessity of remembering to effect such linespacing operation in order to effeet a proper spacing between entries onthe record sheet, it being customary to take care of such entries in themanner stated when said. special automatically operating means are notemployed.

If desired the carbon sheets may be of a length to correspond to thelength of the bill sheet instead of the record sheet, and in thiseventthe carbon sheet will be reis written and will be introduced and fedforward with each newly introduced bill sheet.

While I have described some of the uses to which the devices of myinvention may be put, it will be understood that said devices arecapable of a wide range of uses and may be employed wherever they may befound available, and that some of the devices may be employed withoutothers.

It will also be understood from the foredevices of my invention may bereadily embodied in existing machines now on the market, such, forexample, as the No. 20 Yost machine without modifying, or materiallymodifying, the structural features of said machine as they now exist.
